Looking at the document at:
http://dustyoldcomputers.com/pdp-common/reference/drawings/peripherals/docs…
The picture, though extremely fuzzy, matches my panel in the
organization of legends and breaks in line. Since I have what I think
is a complete RF08, and pieces of the drive (RS08), I think it is safe
to conclude that I have the panel from an RF08.
However, the panel is designed to actually hold up to 8 lights of 36
bits each. I have to believe that DEC used this setup for any number of
light panels.
For photos of the drive electronics, controller electronics, power
supply, platter and display and display measurements, see:
https://drive.google.com/open?id=0B2v4WRwISEQRTkVRX2NPMThILWM
I posted detail display panel photos and measurements in subfolder
Display of this Google Drive folder (RF08-RS08)
The main folder has photos of the drive (RS08) electronics and the
controller (RF08) electronics, etc. (The very first photo shows some
mouse droppings / seeds, which I cleaned up (though I did not entirely
disassemble the thing), and are less apparent in subsequent photos (I
recall there being even more extensive cleaning after the simple
vacuuming I did before taking most of the photos). There is also a
photo of the power supply and the (now separated from the container)
platter and a head or two as well as a photo of the display panel.
In the Display sub-folder are photos of the panel and its components,
and a text file with measurements.
Apologies in advance for the photo quality of the display. I didn't
want to use a flash, and so there was some camera shake, even with IS.

So here's the writeup on the RK11-C insert:

The unusual light pattern should allow us to know, instantly, if we see one.

Hi Jay
Is this what you want me to look at with a view to panel
reproduction ?

I apparently didn't create the sharable link I intended to.

No, not looking for a reproduction. Just posted it in case it would help folks with a
possible RK11-C display panel concept.

Interesting. We also have a RF08 / RS08 combo. It came with two PDP-8/L
machines. I am not sure if both PDP-8/L CPUs were connected to the RF08
simultaneously or how it was connected once upon a time since all cabling
has been removed prior to us getting to it. The front panel look exactly
the same. The drive and controller sits in a full height cabinet with the
drive in the middle and the controller at the top.
What is the plan with your RF08/ RS08? Is it possible to get it complete or
is just parts? The RS08 seems to be a DF32 on steroids. The question is if
it would be possible to have our unit working some day? Anyone tried to get
these things to run?

I ran mine under TSS/8, 32 years ago, when there was still such thing as
a timing track writer. It flaked out about 30 years ago but I still have
it. Anyone have any ideas about what to do for air filters? IIRC you're
supposed to replace them every 6 months, so I need about 70 to get caught up.

That matches the arrangement in the document I referred to. I doubt
very much that they would have both been connected. Presumably just one
of them. The manual I had might give you some clues - according to the
manual it is compatible with an PDP-8/I, PDP-8/L, LINC-8 and PDP-12.
So it is probably just a matter of connecting it to the 8/L on the bus
properly and making sure the bus is properly terminated. See Figure 2-5
in the doc, and compare the signals with the 8/L bus connectors, I suppose.

I would think you could probably get yours working - if the platter and
heads are OK.
When I was younger and more foolish, I didn't realize that I had
basically the entire thing. So I disassembled the drive itself. ( 8P
Stoooopid mistake, I know). I still have the platter, motor, shock
mounts etc., but I don't think I have the housing cover or the base
plate - though I haven't gone and looked for them.
I think I have all of the electronics, power supplies, some of the heads
(but probably not all of them).
So, I don't have any hope of getting mine running. I would be happy to
part with it at a reasonable price, but am not really interested in
shipping them - it would be a very time consuming endeavor for me, and
likely very expensive for any buyer to ship the pieces.
